Penny Battery Flashcard

Front

What is an ion?

Back

An ion is an element that has an unequal number of protons and electrons.

Front

What is a cathode?

Back

A cathode is an electrode that is more willing to accept electrons.

Front

What generates electricity in a penny battery?

Back

The electricity in a penny battery comes from the chemical reaction of zinc and copper.

Front

Why can't protons move through the wire?

Back

Protons cannot move through the wire because they are too large.

Front

What is zinc in the context of a penny battery?

Back

Zinc would be an example of an anode.

Front

What is an anode?

Back

An anode is the electrode where oxidation occurs, and it is the source of electrons in a circuit.

Front

What is a cathode's role in a battery?

Back

The cathode is the electrode where reduction occurs and accepts electrons.

Front

What is the function of an electrolyte in a battery?

Back

An electrolyte is a substance that conducts electricity by allowing ions to move between the anode and cathode.

Front

What is the chemical reaction in a penny battery?

Back

The chemical reaction in a penny battery involves the oxidation of zinc and the reduction of copper ions.

Front

What is the role of electrons in electricity?

Back

Electrons are negatively charged particles that flow through a conductor to create electric current.
